GEORGE A. KNOX, OF DEXTER, NEW YORK.

PLOW.

esseci.

To all whom it may concern:

Be it known that I, GEORGE A. KNOX, a citizen of the United States,residing at Dexter, in the county of Jefferson and Sta-te of New York,have invented certain new and useful Improvements in Plows, of which thefollowing is a specification.

The object `.of the present invention is to provide in a disk plowimproved means for supporting the front furrow wheel, and for raising.and lowering the main frame relatively to the said wheel, as well asmeans for holding the frame in adjusted position.

Another object is to provide improved means for adjusting the frontfurrow wheel and the draft devices to furrows of dierent widths.

With these objects in view, the invention consists in a novelconstruction and arrange- {ment of parts to be hereinafter described andclaimed, reference being had to the drawings hereto annexed, in which-Figure 1 is a plan view of the implement. Fig. 2 is a perspective viewof the front furrow wheel supporting means. Fig. 3 is a perspective viewof a portion of such supporting means. Fig. 4 shows the fastening meanshereinafter referred to. Fig. 5 is a fragmentary plan view showing amodification.

Referring more particularly to the drawings, the main frame of theimplement comprises beams 10 and 11, which are rigidly secured together,and held in spaced relation by a spacing block 12. The beam 10 has atits rear end a laterally directed portion 13 which carries one of thedisks 14, and the beam 11 has at its rear end a similar laterallydirected portion extending parallel to the portion 13, and carrying theother disk 15. Suitable bearings are provided for the axles of thedisks, and each disk is provided with a scraper 16.

The main frame is supported by a land wheel 17, and front and rearfurrow wheels 18 and 19, respectively. Suitable means, cooperating withthe land wheel support, are provided for raising or lowering the mainframe relatively to said wheel, and as such means are well known, andform no part of the present invention, a detailed description thereof isthought unnecessary.

To the front end of the beam 10 is securely bolted, or otherwisefastened a casting in the shape of a plate 20 having a series ofparallel slots indicated respectively Specification of Letters Patent.

at 21, 22 and 23. On this plate is mounted an arched member 24 carryingthe aXle of the front furrow wheel, and having a base 25 which engagesthe top of the plate, and fits between parallel ribs 26 formed thereon.The arched member is securely held in place on the plate by a U-bolt 27,the Shanks of which pass through the slots 21 and 22, and throughnotches 28 made in opposite edges of the base 25. The shanks of the boltproject a suitable distance above the base, and on the projecting endsare screwed nuts, which upon being tightened up, securely fasten thearched member to the plate 20. On the bottom of the plate is a notchedrib 29 which is engageable by the bend of the bolt, and which assists tohold said bolt in place.

The slots 21 and 22 extend transversely of the implement in order thatthe arched member 24 may be adjusted on the plate 20, the adjustmentbeing laterally with respect to the main frame. This adjustment of thearched member is provided in order that the front furrow wheel 18 may beset to furrows of different widths.

The means for raising and lowering the main frame relatively to thefront furrow wheel, and for holding the frame in adjusted position,comprise the following instrumentalities: The outer end of the archedmember 24 is formed with a vertically disposed tubular portion 30 whichforms a bearing. The aXle 31 of the front furrow wheel is formed with avertical spindle 32 which is ournaled in the bearing 30, whereby apivotal support for the aXle is had, and the furrow wheel is thereforefree to swing in the direction of the main frame, to facilitate theturning of the implement.

The spindle 32 rises a suitable distance from the bearing 30, and isloosely encircled above the same by a sleeve 33. A key 34 passingtransversely through the spindle below the sleeve, prevents the latterfrom slipping down on the spindle. To the arched member is fastened asegment rack 35, to which is fulcrumed, at one of its ends, a hand lever36, which is operatively connected by a link 37 to the sleeve 33. Thelever carries a spring latch 38 which engages the teeth of the rack forholding or locking the lever at adjustment.

The main frame is raised or lowered with respect to the front furrowwheel by means of the hand lever 36, and upon locking the saine, theframe is securely held in adjusted position. The sleeve 33 does not gripthe spindle 32, and thelatter is therefore free to swing in the bearing30 as already described.

At 39 is indicated a draft tongue which is rigidly securedv to a lateralbend 40 made in the upper end of the spindle 32, so that when theimplement is at work, the front furrow wheel is held in line; and when aturnfis made, said wheel swings around with the tongue, therebyfacilitating the turning movement of the implement.

The tongue 39 is secured to the bend 40 by a casting 4l which is rigidlysecured to the tongue, and has a pair of spaced arms 42 formed at theirouter ends with sleeves 43 in which the bend 40 is received. Set screws44 passing through the sleeves, securely fasten the casting to the bend.This method of attaching thecasting to the bend, permits adjustmentthereon.

To the front end of the beam 10 is bolted a bracket 45, to which thedraft plate 46 is connected for a threehorse hitch. For a two orfour-horse hitch, the draft plate is removed from the bracket, andconnected to the plate 20 by means of a hook-shaped bolt 47 which' ispassed through the slot 23, the hook portion of the bolt engaging anotched rib 48 onthe bottom of the plate, whereby a-more secure hold ishad. The slot 23 extends transversely of the main frame, and itisprovided in order that the draft may be adjusted to the width of thefurrow.

In Fig. 5 is shown a modification of the connection between the draftdevices and the axle of the front furrow wheel, which permits tlietongue to be dispensed with. The draft plate 46 is mounted as before,and has connected to its outer end, one end of a link 60. The other endof this link is connected to an arm 6l, secured to, and projectingforwardly from a sleeve'62, which is mounted on that portion of the axle31 which extends laterally from tlie-main frame. Vhen the team is makinga turn, the draft plate swings, and through the connection described,the aXle is caused to swing in its bearing 30, thus swinging the frontfurrow wheel around as before.

In the drawings I have shown the invention applied to a gang disk plow,but it is to be understood that it may be applied to single disk plowswith equal facility, and furthermore, various minor changes in thestructural details may be resorted to without a departure from theinvention.

I claim:

l. In a plow, a frame, a plate carried at the front end thereof, andhaving slots eX- tending laterally of the frame, a furrow wheel supportmounted on the plate, and having its base notched on opposite sides, aU-bolt having its shanks passing through the slots of the plate andthrough the notches of the support, and nuts screwed on said shanks, andengageable with the base of the support.

2. In a plow, a frame, a slotted plate car,

ried at the front end thereof, the slots eXi GEORGE A. KNOX. lVitnessesFRED. E. lVooD, O. M. Woon. l
